How can I ensure responsible and appropriate use of the internet?

Well, I as the Technology Director can utilize our district's internet filter and report on any misuses, or ATTEMPTS of misuses of the internet. However, the classroom teachers will not have that capability. They will have to be an alert and attentive presence when the students are online, but they can not monitor every student at the same time. I do expect them to know which students are likely to try to misuse this resource and monitor them closely.
